Content update: Summer 2023 updates to 7th grade math courses!
We are thrilled to announce the release of exciting updates to our 7thgrade math curriculum (and beyond) in Summer 2023!
Please note that these content updates may affect the Mastery percentages of your students. When new content is added or old content is removed, the overall number of skills in a course changes, which can impact Mastery percentages.
For example, previously a student may have mastered 90 out of 100 skills. However, after the update, with new content added and some removed, they might now have mastered 90 out of 110 skills. This would result in a decrease in their Mastery percentage from 90% to 82%.
With these specific updates to the courses, we anticipate varying levels of mastery decrease. The maximum changes are outlined below:
Course  Max mastery % decrease 
7th grade math  5.0% 
EngageNY 7th grade math  3.1% 
Illustrative Mathematics 7th grade  0.9% 
Get ready for Algebra 1  0% 
Arithmetic  1.5%
